Continuing our teaching series of ECGs donated by Jenda Enis Štros, ECG 4 of 6 shows a new occurance of huge T wave inversions in the precordial leads.  Since this is the area that was stented (left anterior descending artery, anterior wall of the LV), we immediately should think of re-occlusion of the artery.  In a newly-placed stent, the danger is thrombosis (blood clot).  The patient had no chest pain at this time.

Here are links to all six of the ECGs in this series:
